Duncan Ward, head of commercial vehicles at BCA, said: “The LCV market has seen continued value growth throughout much of 2016.
"There has been steady demand for vehicles to service online shopping delivery, the construction and civil engineering industries and the small business and entrepreneurial start-up sector.
"BCA continues to experience plenty of demand for tippers and dropsides, Lutons and larger panel vans, the latter often going back to work to service the online shopping sector.”
Ward added “However, volumes are rising and buyers will have more choice in the weeks ahead.
"This underlines the importance of appraising and valuing vehicles sensibly, as this builds buyer confidence and delivers benefits for buyers and sellers alike.
"BCA continues to innovate in this area, with the unique BCA Video Appraisal for LCVs providing a valuable tool for Live Online bidders who do not get to see the vehicle ‘in the metal’.”
